Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145482, here are decompositions:

5 + 145477 = 145482
11 + 145471 = 145482
19 + 145463 = 145482
23 + 145459 = 145482
31 + 145451 = 145482
41 + 145441 = 145482
59 + 145423 = 145482
83 + 145399 = 145482

Showing the first eight; more decompositions exist.
